Sensitive stomach dog food — what to look for and which brands help

Q: What should you look for in a sensitive stomach dog food?

Adding a probiotic. A probiotic can help during the transition. Protexin Pro-Kolin is one we stock and is well-reviewed by UK vets, but speak to your vet before adding anything if your dog is on other medication.

If your dog has unpredictable stools, frequent wind or vomits bile on an empty stomach, the cause may be a sensitive stomach rather than an illness. This guide covers the signs, the most common triggers, and which specialist formulas genuinely help — with options we currently ship across the UK.

What are the signs your dog has a sensitive stomach?

Most dogs with a sensitive stomach show one or more of:

Loose or inconsistent stools that aren't explained by a sudden change or infection
Stools alternating between soft and firm without a clear pattern
Bile vomiting first thing in the morning, especially in younger dogs
Foul-smelling gas more than a couple of times a week
Eating grass often

What are the most common sensitive stomach triggers in dogs?

Three small bowls with single-protein samples: salmon, duck and white fish on a wooden surface — Novel-protein trials: salmon, duck, white fish.

Trigger	Frequency	Fix
Chicken	Most common protein	Limited-ingredient novel protein
Wheat / gluten	Common	Wheat-free formula
Beef	Second-most common	Switch to duck, salmon, white fish
Additives & colourings	Common	Pick a recipe with no E-numbers

What should you look for in a sensitive stomach dog food?

Named, single protein at the top of the ingredient list, not "meat and animal derivatives".
Limited ingredients — fewer items on the label.
No artificial colours — avoid E numbers in the ingredients panel.
Added prebiotics or probiotics — supports the gut microbiome during the switch.

Which sensitive stomach dog food brands do we recommend?

Skinner's Field & Trial Salmon & Rice — single-protein, wheat-free.
Burns Sensitive Pork & Potato — original Burns recipe.
Burns Hypoallergenic Chicken & Rice — chicken-based alternative.
Harringtons Grain Free Salmon — gentle grain-free fish recipe.

How long does sensitive stomach food take to work?

Sensitive stomach formulas typically take 4-6 weeks to fully settle the gut. If no improvement after 8 weeks, move to a different novel protein — duck first, then salmon — and reassess with your vet.
